BACKGROUND: Improving the philtrum morphology of patients with a secondary cleft lip deformity has been a challenge in cleft care. Combining fat grafting with percutaneous rigottomy has been advocated for treatment of volumetric deficiency associated with a scarred recipient site. This study assessed the outcome of synchronous fat grafting and rigottomy for improvement of cleft philtrum morphology.
METHODS: Consecutive young adult patients ( n = 13) with a repaired unilateral cleft lip who underwent fat grafting combined with rigottomy expansion technique for enhancement of philtrum morphology were included. Preoperative and postoperative three-dimensional facial models were used for three-dimensional morphometric analyses including philtrum height, projection, and volume parameters. Lip scar was qualitatively judged by a panel composed by two blinded external plastic surgeons using a 10-point visual analogue scale.
RESULTS: Three-dimensional morphometric analysis revealed a significant (all P < 0.05) postoperative increase of the lip height-related measurements for cleft philtrum height, noncleft philtrum height, and central lip length parameters, with no difference ( P > 0.05) between cleft and noncleft sides. The postoperative three-dimensional projection of the philtral ridges was significantly ( P < 0.001) larger in cleft (1.01 ± 0.43 mm) than in noncleft sides (0.51 ± 0.42 mm). The average philtrum volume change was 1.01 ± 0.68 cm 3 , with an average percentage fat graft retention of 43.36% ± 11.35%. The panel assessment revealed significant ( P < 0.001) postoperative scar enhancement for the qualitative rating scale, with mean preoperative and postoperative scores of 6.69 ± 0.93 and 7.88 ± 1.14, respectively.
CONCLUSION: Synchronous fat grafting and rigottomy improved philtrum length, projection, and volume and lip scar in patients with repaired unilateral cleft lip.
CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
